Hi,

Working on a Samsung 50" Plasma TV that have been mounted too hard to
the wall, so the backplate have pushed the Y-MAIN board and made a
short.

One MOSFET have touched ground, maybe the GATE,
four N MOSFET IXTK62N25 have been changed to similar MOSFET type.
And a FUSE on the Y-MAIN board have been changed(Near the Vs power
connector)
Now there is picture buts is pink, and very bad..

When just turned on its looks like this:

After few secs its gets pink, you can see MENU etc badly

The black area goes away after some minutes.


What can be wrong?

The button locaten on the board in the middle, have been pussed, have
it reset something?
also there is some DIP switches EXT, INT etc - right now on EXT.

Model: Samsung HP-P5071
S50HW-XD03
50"HD D3.0 Y-MAIN

Some manuals he

Looks as if its been 'squicked'

Found a bad fuse also on the X board, changed it, and now there is
fine picture on it.

BUT picture is very red colored. MENU seems fine, maybe alittle red,
but picture is very very red.

What can that be? What board to look on?

Calibration?
